GM crops beneficial, but should be used with care

Genetically modified crops should first be made to go through preliminary tests and tried on a small scale before they are put to large scale use, Prof Krishna Dronamraju, president, Foundation for Genetic Research, Houston, USA, has said.

"I am not completely against GM crops. But research has shown that GM technology may have some undesirable results such as toxicity and allergenic effects on some individuals. Preliminary testing on a small scale is necessary before approving large scale application," he told HT.
